LUBRICATOR FOR CYLINDERS.

SPECIFICATION forming part of Letters Patent 1\To. 451,928, dated May 12, 1891.

Application filed September 29, 1890. Serial No. 366,451. (No model.)

To all whom it may concern:

Be it known that I, OLIVER W. GRIFFITHS, of Brooklyn, county of Kings, and State of New York, have invented certain new and 5 useful Improvements in Lubricators for Cylinders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

[ My invention has relation to devices for carryinglubricants in contact with the inner surfaces of cylinders, which devices are known as lubricators, lubricant-holders, cylinder-lubricators, tire, and are chiefly I intended for use in connection with cylinders and pistons of hydraulic engines, but applicable in other situations.

The principal object of my invention is the production or provision of simple, cheap, dur- 2o able, and eifective means of mounting and securing the material of the holder or carrier upon the ring by which it is held in proper position. To attain this object and to secure other and further advantages in the matters of construction, operation, and use, my improvements involve certain novel and useful features of invention, as will be herein first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a sectional elevation upon a plane cutting through a cylinder and across the piston-rod, showing my improved lubricator in place for use. Fig. 2 is an axial View, partly in section and partlyin elevation, showingafragment each of thecylinder piston-rod and piston or follower. Fig. 3 is a plan view showing the perforated carrierband developed or extended and disconnected from other parts. Fig. 4: is a View in perspec- 0 tive showing a bracket or clip connected with the lubricator-band. Figs. 5, 6, 7, 8, and 9 are detail views, each partly in section and partly in elevation, showing the material of the carrier applied to the carrier-band by metallic fastenings and illustrating varying but equivalent modes of locking the ends of the fasteners.

In all the figures like letters of reference, wherever they occur, indicate corresponding parts.

The material of which the carrier itself is made may be of any character whatever, so long as it is suitable for the purpose; but I prefer natural wool of long fiber and as it is plucked from the hide.

Heretofore sheep-pelts have been employed in lubricators; but from the very nature of this material, the union between the wool and the skin being so easily destroyed, they have been found to deteriorate almost from the commencement of their use and to require frequent renewal-a difficult, tedious, and ex pensive operation. To obviate this I take separate and independent tufts of the material, whatever it may be, as at a a a, and secure them to a metallic band A by metallic fastenings. (Represented at b b.) The band A is perforated at suitable intervals, as at c c, Fig. 3, to admit the fastening's. These may be of wire and held on the'inner side in any secure way by twisting the ends, as in Fig. 5; by upsetting or riveting both ends, as in Fig. 6; by upsetting one end and applying a thumbnut d upon the other, as in Fig. 7; by use of two thumb-nuts d, as in Fig. 8, or by use of a rod or wire 6, Fig. 9, which receives the tufts and is in turn secured or locked to the band in any suitable way, as indicated in said figure. The manner of clinching the ends of the fasteners may be varied in many ways. The material thus applied cannot work loose, and as it brushes back and forth lightly upon the inner surface of the cylinder B, carrying the lubricant (oil or grease, 8:0.) in contact therewith, it will need no attention for avery 8 5 long time, the actual wear upon it being insignificant. If it should ever become necessary to replace one or more tufts, the repair is The ring or band, with the material secured I00 thereon as above described, is shown as held in place with respect to the cylinder and piston by use of clips or braces E, which are joined with lugs I-I, applied to the inner face of band A, as by bolts 71-, and secured to the piston or follower by the follower-bolts i. This brace is perforated, as at Z, for the reception of the follower bolt. The bolt 70 slides in the slot m, so that it may be set at any desired point thereof and it enters between the open jaws n 71, (forming an open mouth) in order that the band may be adjusted 0n the bolt to bring it to the desired distance from the piston or follower without disturbing the bracket. The jaws n n are open, so that they may be easily slipped upon bolt 70 and under nut 0 or Washers 0 after the bracket has been located in place, and they have projections 19 p at their extremities to prevent the clips or braces from becoming separated from the ring unless the nut 0 is purposely unturned.

The carrier is durable, easily and quickly applied, and cheaply made.

Having now fully described my invention,

what I claim as new herein, and desire to secure by Letters Patent, is

1,. A cylinder-lubricator consistingof a band or base, a lubricant-carrying surface composed of a series of tufts, and separate and independent fastening devices for each tuft, whereby any tuft may be removed from the base without disturbing the other, substantially as explained.

2. In a cylinder-lubricator, a band or base bearing the lubricant-carrier, composed of a series of tufts secured by separate and independent fastening devices, said base being locked at the ends by removable bolts, forming thereby a continuous band, substantially as explained. V

In testimony that I claim the foregoing I have hereunto set my hand in the presence of of two witnesses.
